Hy guys,
I have problems to import nessus xml report scan in metasploit framework.
I have installed the new nessus 4.2.2 version and when I try to import the report file with db_import_nessus_xml I receive this error:

msf > db_import_nessus_xml /root/xxx.nessus
[-] Error while running command db_import_nessus_xml: undefined local variable or method `file_contents' for #<Msf.DBManager:0xb7330bdc>

I save the xml report in nessus version 1 because the version 2 is not already supported by metasploit framework.

Any idea?
Thx!
